The research showed that the estimates of body fat percentage according to BMI measurements and the formula were valid, but did tend to overestimate the body fat percentage. Since fat tissue has a lower density than muscles and bones, it is possible With a well engineered weighing system, body density can be determined with great accuracy by completely submerging a person in water and calculating the volume of the displaced water from the weight of the displaced water.
